Certified Rhythm Analysis Technician (CRAT) Practice Exam

The choice regarding the use of the same amount of gel on each electrode during the tracing is not considered a guideline for proper use of disposable electrodes. The primary guidelines focus on ensuring the electrodes are stored and used safely and effectively.

Keeping unused electrodes in a sealed plastic bag helps maintain their integrity by preventing drying out, which is essential for them to function properly. Checking the expiration date ensures that the electrodes are still effective and safe to use, as expired electrodes may not adhere properly or could provide inaccurate readings. The practice of using disposable electrodes for only one ECG ensures hygiene and prevents cross-contamination, which is vital in a clinical setting.

While it is beneficial to use an appropriate amount of gel for optimal conductivity, consistency in gel application is not a formal guideline. It is more of a recommended practice than a mandatory rule for the use of disposable electrodes.
